BACKGROUND OF THE INVENTION Field of the invention This invention relates to hydroxymethyl-substituted phenylindans and polymers thereof and to the preparation of these condensants and polymers.

Description of the prior art There is a continuing demand for low cost film-forming materials with improved physical properties which can be used as supports for photographic elements. Many of the currently available film-forming compositions that exhibit good physical characteristics are commercially unattractive owing to the cost of the component ingredients or the difiiculty of the manufacturing conditions.

The compound 1,1,3-trimethyl--carboxy-3-(4-carboxyphenyDindan is a commercially available material, generally referred to as phenylindan dicarboxylic acid or, abbreviated, PIDA. Means for the preparation of PIDA have been disclosed by Petropoulous in, for example, U.S. Pats. 2,780,609; 2,830,966 and 2,873,262. U.S. Pat. 2,780,- 609 describes the use of PIDA as a plasticizer for vinyl chloride polymers. U.S. Pat. 2,830,966 relates to polyester resin compositions comprising an unsaturated poly- 3,803,096 Patented Apr. 9, 1974 ester resin and a polymerizible compound containing a vinylidene group, wherein the polyester resin is prepared by reacting a polyhydric alcohol with an alpha, beta-unsaturated polycarboxylic acid and PIDA. U.S. Pat. 2,873,- 262 relates to a process for preparing alkyd resins comprising reacting a polyhydric alcohol with PIDA.

The preparation of PIDA has also been described by Petropoulous et al., in U.S. Pat. 3,102,135.

Copolymers of PIDA with terephthalic acid and ethylene glycol have been described in Belgian Pat. 731,258 and Netherlands Pat. 6905547 and its reaction with bisphenols has been described by Hamb in Belgian Pat. 748,510.

Preparation and uses for l-(hydroxyphenyDindanols are described in U.S. Pats. 2,754,285, 2,819,249 and 2,979,534.

Diisocyanatoindans and diisothiocyanatoindans and polymers prepared therefrom are described in U.S. Pats. 2,855,385 and 2,855,420.

Dicarboxylic compounds which can be employed to advantage in preparing polyesters from the dihydroxymethyl compounds of this invention include succinic acid, glutaric acid, adipic acid, pimelic acid, azelaic acid, sebacic acid, Z-methyladipic acid, diglycolic acid, thiodiglycolic acid, fumaric acid, cyclohepane-1,3-dicarboxylic acid, cyclohexane-1,4-dicarboxylic acid, cyclopentane-1,3-dicarboxylic acid, 2,S-norbornanedicarboxylic acid (the abovedescribed acids being useful either as the cis or trans form), phthalic acid, isophthalic acid, terephthalic acid, t-butylisophthalic acid, phenylenediacetic acid, phenylenedipropionic acid, 2,6-naphthalenedicarboxylic acid, 1,4-naphthalenedicarboxylic acid, 1,5-naphthalenedicarboxylic acid, 1,7-naphthalenedicarboxylic acid, 4,4'-diphenic acid, 4,4-sulfonyldibenzoic acid, 4,4'-oxydibenzoic acid, binaphthyldicarboxylic acid, 4,4'-stilbenedicarboxylic acid, and 9,10-triptycenedicarboxylic acid.

Although the dicarboxylic acids useful in the practice of this invention can be employed in the free acid form, it is often more advantageous to utilize a bifunctional derivative. For example, the corresponding acid anhydrides may be used where they are available. Other useful bifunctional equivalents include the lower monohy dric alcohol or phenyl esters of dicarboxylic acids and the dicarboxylic acid halides, e.g., the chlorides or bromides.

The molecular weight of the linear condensation polymers of this invention can vary over wide ranges; it has been found that polymers having a molecular weight of at least about 10,000 are useful. Compounds having a molecular weight from about 30,000 to 100,000 are particularly desirable. The compounds of this invention are further characterized by their inherent viscosities. Generally, the subject film-forming polymers have an inherent viscosity of about 0.1 to about 0.8 and the polymers preferred as supports for photographic elements have an inherent viscosity of about 0.5 to about 0.8. The inherent viscosities are measured at 25 C. in 1:1 (by wt.) phenolzchlorobenzene at a concentration of 0.25 g. of polymer per ml. of solution unless otherwise specified.

The glass transition temperatures of the polymers of this invention can be determined by differential scanning calorimetry as disclosed in The DSC Cell and Accessories Instruction Manual for the 900 Thermal Analyzer and Modules, sold by E. I. du Pont de Nemours Instrument Products Division.

Film-forming as used in this invention refers to a material which will provide a self-supporting film of the material when cast or extruded, for example, when cast in sheets of from 1 to 7 mils thickness.

It is appreciated, of course, that the physical properties of the broad class of polymers of this invention, such as, for example, the glass transition temperature (T,,), yield strength, break strength, Youngs modulus and the like, can be varied over a wide range. Polymers with properties in a particular range can be easily obtained by judicious selection of appropriate diol and dicarboxylic components and suitable mixtures thereof. The proper choice and proportions of the monomeric components can be determined by test procedures well-known to those skilled in the art of making condensation polymers.

As indicated in the general formula set out hereinabove, the linear condensation polymers of this invention include polyesters, polyurethanes and mixed polyester-polyurethanes. Generally, any procedure known in the art for making linear condensation polymers can be used in preparing the polymers of this invention. The following are examples of processes that may be utilized to produce the linear polymers of this invention.

(a) The interfacial procedure can be utilized to make the polymers by converting the diol to the bischloroformate. The preferred time of reaction is a function of all other variables and, as such, is governed by the viscosity desired for the polymer. Generally, the reaction can be monitored by sampling and thus the preferred polymerization time chosen. A variety of solvents may be employed to provide a broad range of temperatures and solubilities as desired. Suitable solvents include the chlorinated hydrocarbons such as, for example, chloroform, dichloroethane, propylene dichloride, dichlorobenzene and the like.

(b) Polymers, according to this invention, can be prepared by a solution procedure whereby the reactants are placed in solution in the presence of an acid acceptor, e.g., a Lewis base such as, for example, pyridine. The Lewis base can also be present in excess and thus serve also as the solvent.

The ester interchange procedure of synthesizing polymeric esters both by the melt process and the powder process can advantageously be used to make the polyesters of this invention, in particular, the powder process can be used advantageously when the first stage polymers can be crystallized. In a preferred embodiment, these techniques may be used in combination with a solvent crystallization step to aflord film-forming polyester having improved physical properties. The solvent crystallization procedure generally involves contacting melt process polymer with a solvent at ambient temperatures. Suitable solvents include acetone, Z-pentanone, ethyl acetate, acetic acid, toluene and the like. The treated material is separated from the solvent by any conventional procedure and put through the powder process. The melt process is advantageously conducted in the presence of a catalytic agent. Useful catalysts for the transesterification reactions include the carbonate, oxide, hydroxide, hydride and alkoxide of an alkali metal or an alkaline earth metal, a compound of a Group IV-A metal of the Periodic Table, e.g., titanium isopropoxide, organometallic halides and complex alkoxides such as NaHTi(OC H and the like.

The film-forming materials of this invention can be generally extruded or cast into flexible supports and used in various layer arrangements and structural combinations. Generally, the flexible supports prepared from the polymers of this invention are treated by any convenient method to improve the adhesion of superimposed coatings or layers. Useful procedures include subbing with conventional subbing agents for polymer supports, contacting with a chemical agent such as sulfuric acid, electron bombardment, and the like. The film-forming polymers of this invention are used to advantage as flexible supports for photographic silver halide and other lightsensitive systems as well as for multi-layer elements used in color photography and diffusion transfer processes.

The following examples are included for a further understanding of the invention. It should be understood that where equations are given, they represent the overall reaction described in the particular example without regard to possible mechanisms.
